Ubuntu 22.04 LTS must disable account identifiers (individuals, groups, roles, and devices) after 35 days of inactivity.

Description
Inactive identifiers pose a risk to systems and applications because attackers may exploit an inactive identifier and potentially obtain undetected access to the system. Owners of inactive accounts will not notice if unauthorized access to their user account has been obtained. Operating systems need to track periods of inactivity and disable application identifiers after 35 days of inactivity.

Who does this work

6 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-260547r1015009_chk)

Verify the account identifiers (individuals, groups, roles, and devices) are disabled after 35 days of inactivity by using the following command: Check the account inactivity value by performing the following command: $ grep INACTIVE /etc/default/useradd INACTIVE=35 If "INACTIVE" is set to "-1" or is not set to "35", is commented out, or is missing, this is a finding.

Fix Text (F-64184r953453_fix)

Configure Ubuntu 22.04 LTS to disable account identifiers after 35 days of inactivity after the password expiration. Run the following command to change the configuration for adduser: $ sudo useradd -D -f 35 Note: DOD recommendation is 35 days, but a lower value is acceptable. The value "0" will disable the account immediately after the password expires.
